This results in excellent fatigue resistance, chemical resistance, impact resistance, and environmental properties. This includes shrinkage, which results with less stresses in the finished pipe and excellent mechanical properties. The pipe components (binding material and reinforcements) are entirely determined by the type of fluid handled, the type of chemical, the percentage concentration of the chemical, and the service temperature. Depending on the application, different types of resins are used, that could lead to the following categories.
GRP When using iso-pthalic resin. The main binding materials for common applications like service water and utility water are polyester resin and ortho-pthalic polyester resin.
GRV / FRP / RTR / RTRP When using vinyl ester resin as a binding material for specific chemical resistance and slightly elevated temperatures up to 85°C.
GRE When epoxy resin is used as a binding material, it can withstand temperatures of up to 120°C.
